Archer skill build

Hello i am a level 16 archer. I am wondering what a good skill build would be for an archer so i know where to put my future skill points.
My skill build so far: 5 focus, 2 Blast shot, 1 avian scream, 1 thorn shot, 2 meditation, 1 restore, 3 evasion. good-bad?

I am only level eight but from what I have seen I would say focus and blast shot would be the top two.

I generally follow the philosophy it is better to max out skills rather than spend points across loads of diffrent skills.
